Hello, I am looking at turning my kx100 into a sumo. I'd like to keep the stock rear wheel, it's a 16. I'll try and run 100/90 pirellis in place of the 90/100 dirtbike tires, would 110/90 work too? It is a 1.85. They only make the 100/90 in a front version. Looks like you guys just run tubes in tubeless tires from what I've seen. What wheel should I use up front? Can i just use the stock 19s as a beginner for now? That one is a 1.4. Not trying to go too expensive here.
